782853270

Overview

The Würth Elektronik 782853270 is a surface-mount ferrite bead from the WE-CBA series, designed for EMI suppression in compact electronic assemblies. Housed in an 0805 (2012 metric) package with dimensions of 2.0 mm x 1.25 mm x 0.9 mm, it provides an impedance of 27 Ω at 100 MHz. The component supports a DC current rating of 4 A and exhibits a maximum DC resistance of 15 mΩ. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Compact 0805 surface-mount footprint for space-constrained designs
• High current handling capability suitable for power line filtering

Applications

• Automotive electronics systems requiring EMI suppression
• General-purpose EMI filtering on data and power lines
• Portable devices needing compact noise suppression components

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before integration. Confirm that the AEC-Q200 Grade 1 qualification aligns with your project's environmental and reliability requirements. Ensure storage conditions adhere to moisture sensitivity levels if applicable.

Selection Notes

Select this component when a low-profile 0805 ferrite bead is required for high-current applications up to 4 A. The 27 Ω impedance at 100 MHz makes it suitable for broadband noise attenuation. Consider the 15 mΩ DC resistance for minimal voltage drop in power-sensitive circuits compared to higher-resistance alternatives.
